AN5246 Application note How to use SMPS to improve power efficiency on STM32WB MCUs Introduction This document describes how the use the SMPS (switched mode power supply) integrated in microcontrollers of the STM32WB Series. It is intended to be used by system archite...
the higher the frequency of the ripple filtered out. You can also consider connecting magnetic beads in series with the output port, and then output, but if you have a DC-DC module behind the power supply, you have to use magnetic beads with caution, because ...
Modems and routers all have a switched-mode power supply (SMPS) that is plugged into an outlet. The EMI created by this SMPS can travel along your electrical wiring and Ethernet cables. You can test this with an AM radio and electric field meter (pictured below). Newer “Gigabit” modems...
I have some basic knowledge of SMPS voltage regulation feedback circuit concepts, and basics of control systems theory, mainly conceptually. I've hacked various PSUs and 5V battery chargers to make them variable voltage supplies. I'd like to learn some more about how power supply engineers det...
Power electronics can supply hundreds or even thousands of amps in some applications. Traces must be robust enough to safely carry the expected currents without overheating. Use Thick Traces The first line of defense is selecting suitably thick copper traces based on the anticipated current. As a ...
How to Select a Power Analyzer 来自 掌桥科研 喜欢 0 阅读量: 6 作者: G Jacob 摘要: Almost all AC-powered electronics products today use switch-mode power supplies (SMPS), most with the potential to generate significant power-line disturbances. Since equipment developers want power supplies ...
LDO regulators feature clean, low noise outputs, but have the drawback of lower efficiency compared to another voltage regulation device, the switch-mode power supply (SMPS). Modern SMPS devices have efficiencies that exceed 90%. However, switching converters deliver noisy outputs due to the rapid...
I recently had a low noise application where I wanted to try to use a very low-cost 3.3 V SMPS; only 50 mA of load current was required. I had an evaluation board which I wired up to power from a 5 V wall wart supply and measured the output with a simple 10× probe. My ...
